WATER-ELEVATOR.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed September 1,1906. Serial No. 332,926.

To all whom it may concern: 7

Be it known that I, STEPHEN E. Mnnnicx, a citizen of the United Statesof America, residingin the city of St. Louis, in the State of Missouri,have invented certain new and useful Improvements in Water-Elevators, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawing, forming part of thisspecification.

My invention relates to a device for exerting pressure upon the water ina well for the purpose of forcingthe water from the well through asuitable pipe to the surface of the ground or to any desired elevation.

Figure I is a view partly in elevation and partly in vertical section ofmy water elevator. Fig. II is a top or plan view of the elevator. Fig.III is a top or plan view of a well with the surmounting platformomitted and the water receiving cylinder and discharge pipe shown incross section taken on line III-III, Fig. I.

A designatesa well having an inbuilt part providing an annular ledge andB is a platform surmounting the well.

l designates a Water receiving cylinder that is vertically positioned inthe well A and spaced from the wall thereof so as to provide an annularwatenreservoir. The lower end of this receiving cylinder which extendsinto the water in the well is mounted upona cylinder supporting circularbase 2 that has an annular channel or groove in which the lower end ofthe cylinder is fitted and the base is provided with a series ofsegmental openings or water passageways 3 through which the water maycirculate in either an upward or downward direction. This circular base2 is seated upon the annular ledge formed by the inbuilt part of thewell. The receiving cylinder supporting base is also provided with acentral orifice 4 through which the water may enter the receivingcylinder.

5 is an upwardly opening and downwardly closing check valve pivoted tothe cylinder supporting base at 6 and adapted to open in an upwarddirection within said receiving cylinder as indicated by dotted linesFig. I. The upward movement of this valve is governed by an upwardlyinclined stop arm 7 which serves to prevent the movement of the checkvalve in opening to a position past the dead center or the pivotal pointof the valve. Located at a suitable distance above the check valve so asto be clear thereof is a plunger seat upon which the plunger can besupported so as not to come into contact with the check valve when thereceiving cylinder is becoming exhausted or theelevator is not beingused.

8 designates a discharge pipe leading from the lower end of the waterreceiving cylinder and extending upwardly through the annular waterreservoir to the exterior of the well. This discharge pipe may beprovided with a faucet 9 through which the water may be discharged intoa trough at the well, and it may be also provided with an extension 8 bywhich the water may be conducted to any desired point before beingdischarged. The pipe extension 8 is preferably provided with a valve 10.

11 designates a plunger that is adapted to operate in the waterreceiving cylinder 1 to exert a pressure upon the water therein for thepurpose of causing water to be forced through the discharge pipe 8. Theplunger is provided with a central orifice 12 that is controlled by anupwardly closing and a downwardly opening check valve 13 which ispivoted to the lower side of the plunger at 14 so as to opendownwardly,the degree of downward movement of the check valve being limited by adownwardly inclined stop arm 15 carried by the plunger.

16 is a rack bar attached by a spider frame to the plunger 11 andextending to the exterior of the well.

17 is a frame mounted upon the well platform and provided with a crossbar 18 to which is secured a guide bracket 19 in which the plunger rackbar operates.

20 is a pinion arranged in mesh with the teeth of the rack bar 16 androtatably supported by a driven shaft 21 journaled in suitable bearingboxes mounted on the frame 17.

22 is a pinion driving gear wheel meshing with the pinion 20 and fixedto a driving shaft 23 that is journaled in suitable bearing boxesmounted on the frame 17. The driving shaft. 23 is equipped with a crankhandle 24 or any other suitable means whereby said driving shaft may berotated.

In the practical use of my water elevator, the operation is as follows:The plunger 11 is first elevated by op erating the driving shaft 23 andthe gear wheel 22 thereon, whereby the pinion 20 geared to said gearwheel is rotated and caused to act with lifting effect upon the rack bar16. As the rack bar is lifted it carters into the receiving cylinder 1through the inlet orifice 4. The parts are then released and theplunger, with its rack bar, descends by gravity with the result ofexerting a pressure against the water in the receiving cylinder 1, as aconsequence of which the water is forced from said receiving cylinderinto the discharge pipe 8 and held under pressure and may be withdrawnfrom said pipe at any point to which the pipe leads. It is to beunderstood that the plunger and the parts associated therewith whichdescend by gravity to force the water from the receiving cylinder 1 mustbe of sufficient weight to produce the necessary pressure against thewater for the delivery thereof through the discharge pipe. It is obviousthat when the plunger is descending to force the water from thereceiving cylinder, the check valves 5 and 13 controlling the inletorifice 4 and the plunger orifice 12 respectively are closedautomatically, thereby preventing the waterfrom being forced from thereceiving cylinder 'ries with it the plunger and the water in the wellenthrough the inlet orifice or through the plunger orifice into theupper end of the receiving cylinder.

For the purpose of providing for the disengagement of the pinion drivinggear wheel 22 from the pinion 21 when the elevator is not in use, I somount the driving shaft 23 that carries said gear wheel that it may beshifted longitudinally in its bearing boxes and form an annular groove23 in said driving shaft that is adapted to receive a dog 25. When thisdog is seated in the groove in the driving shaft as just mentioned, itserves -to hold the driving shaft from longitudinal movement andmaintain the gear wheel in mesh with the pinion 20, but when the dog isWithdrawn from said groove the driving shaft is readily shifted to throwthe gear wheel out of mesh with said pinion.

I claim:

1. The combination of a well having an inbuilt part pro viding a ledge,a water receiving cylinder located within and spaced from the wall ofthe well so as to provide a reservoir, a base formed with a series ofpassageways su1= rounding the receiving cylinder, with an annular groovein which the lower end of the receiving cylinder is fitted, and with, acentral inlet orifice surrounded by the receiving cylinder, a checkvalve for controlling the central inlet orifice and pivoted to the baseat one side of its central inlet orifice, and adapted to open upwardlyand to close downwardly, a discharge pipe leading from the lower end ofthe receiving cylinder, a gravitating plunger adapted to operate in thereceiving cylinder, and formed with a central inlet orifice, and a checkvalve for controlling the central inlet orifice of the plunger andpivoted to the bottom of the plunger at one side of its central inletorifice and adapted to close upwardly and to open downwardly.

2. The combination of a well having an inbuilt part providing an annularledge, a water receiving cylinder located in and spaced from the wall ofthe well so as to provide an annular water reservoir, an annular baseformed with an annular series of passageways surrounding the receivingcylinder, and with a central inlet orifice surrounded by the receivingcylinder, a check valve for controlling the central inlet orificepivoted to the base at one side of its central in let orifice andadapted to open upwardly and to close downwardly, a discharge pipeleading from the lower end of the receiving cylinder, a gravitatingplunger, adapted to oper ate in the receiving cylinder, and formed witha central inlet orifice, and a check valve for controlling the centralinlet orifice of the plunger pivoted to the bottom of the plunger at oneside of its central inlet orifice and adapted to close upwardly and toopen downwardly.
